Van Riemsdyk, who had a goal and two assists in regulation, put a backhander past Craig Anderson on Toronto's first attempt after James Reimer stopped Jason Spezza. He has scored on four of seven shootout attempts overall, including all three this season.

"I don't like to give those away," van Riemsdyk said. "I like to keep those close to the chest, so I have a couple of different things that I maybe think about trying when I'm skating in, and depending on what I see in the goalie, I'll give one of them a shot."

Reimer then made a glove save on Milan Michalek before Raymond beat Anderson to end the game.

The Maple Leafs improved to 4-2 in the shootout.

"I wanted to really shut the door," Reimer said. "You never like giving up a lead in the third and you want to stand in there for the boys, so when it came to the shootout I wanted to stand on my head and give them a chance."

Ottawa fell to 0-4 in the shootout.

"We go out and score the first two and it's a different game, obviously, in the shootout, so it's a collective effort," said Anderson, who made 28 saves through 65 minutes. "I got pieces of both, just not enough, so sometimes you need a little luck."

Toronto's Phil Kessel had a goal and an assist to extend his points streak to six games, and defenseman Jake Gardiner scored his first goal in 20 months.

Reimer, who made 47 saves, is now 7-0-0 at Canadian Tire Centre.

"There's no secret sauce, the ice isn't special, the only thing is obviously it's just a fun place for me to play," Reimer said. "It's just one of those buildings that's loud and it's energetic, and as a player those are the fun games to play."

It was the third time in eight games, and second in a row, the Maple Leafs gave up 50 shots. Toronto won all three of those games, including a 49-save effort by Reimer in a 2-1 shootout win against the Washington Capitals on Nov. 23 prior to a five-game losing streak.

Ottawa, which erased deficits of 1-0 and 3-1, scored twice in the third period to force overtime. Erik Condra scored at 2:23 to cut the lead to 3-2. Erik Karlsson tied it with a power-goal at 10:30.

"It's a game where we get 50 shots," said Senators forward Clarke MacArthur, who also scored on the power play in the first period. "I mean, how many of those ones do you lose? It was like a firing range in the third period there, so we were able to get a couple, and it was good by us.

"It's just a positive thing for us to take forward. You've got to take it forward. I mean, the shootouts are the shootouts. I always feel like you play until the end of overtime and the shootouts, you never know what can happen."

Gardiner put Toronto up 3-1 at 11:37 of the second period on a shot from the right faceoff dot that went through Senators defenseman Marc Methot's legs, with van Riemsdyk sprawled inside the net. The 23-year-old defenseman carried the puck from the left side, high along the Ottawa blue line and past Senators forwards Bobby Ryan and Kyle Turris before making his way to the right circle.

Just before Gardiner shot the puck, a delayed penalty was signaled on Methot, who argued in vain that he had not pushed van Riemsdyk into the goal.

"He pushed me into the goalie and then I just tried to put my head down so I didn't get hit in the face with the puck, and I just saw it right on the ice in the net," van Riemsdyk said.

Gardiner's goal was the fourth of the season by a Toronto defenseman.

Van Riemsdyk extended his points streak to four games when he gave the Maple Leafs a 1-0 lead 1:37 into the opening period. He beat Anderson with a backhand from the goalmouth after Karlsson was called for tripping at the 58-second mark.

MacArthur got the Senators even with a power-play goal at 9:44. He scored 14 seconds after Toronto's Jay McClement was sent off for tripping. MacArthur has six goals and 11 points in his past 10 games.

Referee Brian Pochmara, who had blown his whistle to stop play, immediately waved off an apparent goal by Spezza with 1.3 seconds left in the first period.

Van Riemsdyk set up Kessel's goal on a 2-on-1 at 3:05 of the second after Ottawa center Zack Smith turned over the puck in the Maple Leafs' zone. Smith, who fell to the ice while losing the puck to van Riemsdyk, was given an unsportsmanlike conduct penalty for embellishing his contact with Toronto's Nazem Kadri.

Kessel has four goals and four assists during his point streak.

Defenseman John-Michael Liles, who was recalled from the Toronto Marlies of the American Hockey League on Friday, made his season debut for Toronto, which hosts the Boston Bruins on Sunday.

"It felt good," Liles said. "You try not to doubt yourself. I've played a number of years in this League for a reason, and you just try and remember that. For me, you get sent down to the Marlies and it's an opportunity to play and bring something to a different team.

"I mean, it's the same organization but it's a different team, so you try and do whatever you can, work hard, be a pro, and for me it felt good being back up here and contributing tonight."

Ottawa, which has lost four of five, hosts the Philadelphia Flyers on Tuesday.
